I noticed today that the wall connector for my Polaris 280 is broken and needs to be replaced. If I order this part from Amazon:
Amazon.com : Zodiac D29 UWF Quick Disconnect Replacement : Lawn And Garden Tool Replacement Parts : Patio, Lawn Garden
and use the pressure relief valve from my broken connector pictured here:

will that cover everything I need to make this fix?
Also - what is the best way to remove the broken piece of the connector from the hose?
Thanks
